Big Feelings / NOT OFFERED THIS SESSION
Instructors: Jean Bonasera and Martha Goelzer
4 dogs, 1 hour
Starts October 25
Registrar: Linda Pacioretty
Are you interested in signing up for a beginner class, but have a dog that loses his or her mind in the presence of other dogs or people?
The primary goal of this class is to give dogs an opportunity to habituate to the IDTC training space in a non-stressful way so that they will be comfortable in a group class situation and able to focus on and easily reorient to their handlers in the training space. More generally, the class is designed to strengthen a dog's ability to stay attuned to his or her handler while working on leash around other dogs. We aim to always keep the dogs in the class in the “think and learn” zone, and only gradually introduce the presence of other dogs, beginning with neutral dogs.
We will focus on exercises developed by Suzanne Clothier and Leslie McDevitt. The first class will be a handlers only class, then for each of the 4 weeks following we will work with 2 of the four teams in the class, alternating pairs. During each of those weeks new exercises will be introduced. The other handlers will observe and help with feedback of the working teams and may also have a chance to practice the mechanics of new skills with one of our neutral dogs. On the 6th and 7th week, we will orchestrate having the 4 dog/handler teams together in the space and use distance and gating to help keep dogs in the 'think and learn' zone as we work through skills together.
We will not be working with dogs that are aggressive to dogs or people. Dogs should be comfortable in a crate for 15 minutes at a time.
If you are unsure whether or not your dog is a good candidate for this class, please contact the instructors Jean ([email protected]) and Martha ([email protected]).
Students who submit a registration for this class will be contacted by the instructors for additional screening and information.
